IMO looking at the transits to the natal chart it does look like you will move.
You have both have an unexpected house move coming up. So this I would assume by what you have said is when you sell the house. You have T Uranus in the 4th about to conjunct Mercury. T Uranus has just squared your Jupiter in the 8th. So not sure if this means that you will loose out on some money, maybe you get the raw end of the deal once its sold.
You wife has a similar moving aspect in that she has T Uranus opposite the 4th house... unexpectefully someone will make her make a decision regarding home. I see that the opposition gives her a choice where the conjunction that you have means the moving is right on top of you, not your decision to move, its her's.
I cant see much in a relationship break for you though. I can see that T Jupiter has just past your Venus a couple of weeks ago and T Mars was squaring your Asc back in December. Maybe this is when everything came to a head? T Uranus has just sextiled your NN in the 7th. So I would think this would signify the relationship break for you.
Looking at your wifes chart I see that she has T NN approaching her 7th in less than 1 degree (dont forget NN goes backwards around the chart). The challenging Uranus/Saturn opposition along her 4th and 10th, the house of status and home and T Mars went retro on her Venus in the 2nd in Dec too.
I do think that you will divorce from what you have said and the challenging aspects that you both have. With anything I cant tell if you will get back together, you just need to keep watch on good aspects to the 7th house and the ruler of the 7th and she needs good aspects to in her chart at the same time
.
I wish you Good luck.
